One of the tests was already a flaky timeout: inspector/indexeddb/clearObjectStore.html

 PASS: 'Stats' object store should have been cleared.

 -- Running test case: NoSuchObjectStore
+ERROR: TypeError: this._dispatcher is not an Object. (evaluating 'eventName in this._dispatcher')
 PASS: Should be an error attempting to clear an object store that does not exist.


All 3 test get the same error:
+ERROR: TypeError: this._dispatcher is not an Object. (evaluating 'eventName in this._dispatcher')

In addition, these test will intermittently fail with other inspector tests but fail together more often.
